I was a long time user of an RME Fireface 800, 10 years and then it conked off on me. I was shattered.
I then bought a Universal Audio Apollo 8p. It is absolutely amazing to be able to use the DSP on a hardware device and take the strain off your PC. And the UAD plugins are awesome, especially their preamps, but also things like their Ocean Way Studios plugin. I also plan on picking up one of those Townsend Labs mics one of these days.
The Fireface was just sitting in storage for a while and then I got the bright idea of sending it in for repair. Cost a tonne because they had to replace the motherboard, but now that it's back, I am really stoked.
Unfortunately, the repair cost so much that I would lose a lot of money if I sold it. Stupid of me to repair something based on nostalgia value. But like others have said, the RME stuff is supported for decades, they keep putting out firmware updates. I figure I'll use it for a portable recording/live solution with a laptop.
